In smooth coats, the coat should be soft, close and glossy. Heavier coats with undercoats are acceptable. Coat placed well over body with ruff on the neck preferred and more scantier on head and ears. Hair on tail is preferred furry.
In long coats, the coat should be a soft texture, either flat or slightly wavy with an undercoat preferred. A thin coat that resembles bareness will disqualify the dog.
On the ears, the fur should be fringed. On the tail, the fur should be full and long like a plume. Feathering on feed and legs, pants on hind legs and large ruff on neck is desired and preferred. They should only be groomed to create a neat appearance.
Any color is acceptable; the color may be solid, marked or splashed.
The Chihuahua should move swiftly with a firm, sturdy action, with good reach in front equal to the drive from the rear. From the rear, the hocks remain parallel to each other, and the foot fall of the rear legs follows directly behind that of the forelegs. The legs, both front and rear, will tend to converge slightly toward a central line of gravity as speed increases. The side view shows good, strong drive in the rear and plenty of reach in the front, with the head carried high. The topline should remain firm and the backline level as the dog moves.
Alert, projecting the ‘terrier-like’ attributes of self importance, confidence and self reliance.
